PPRRH335 Intelligent Trace Oxidation Stability Tester
Summary
The instrument can initiate an extremely fast artificial aging process to evaluate the oxidation stability of liquid fuels (gasoline, diesel, biodiesel/fatty acid methyl ester and mixed oil). The results include all volatile and nonvolatile oxides, so complete analysis of sample oxidation stability can be performed in a very short time.
Standard method:
ASTM D 7525 (Gasoline)
ASTM D 7545 (Diesel, Bio-Fuel and Blend) EN 16 091 (Diesel, Bio-Fuel (FAME) and Blend)
Characteristic
For solids and liquids
Fully automated test process saves you time and 20 times faster than traditional methods
Only 5ml test sample is required
The automatic locking function of the safety cover ensures the safety during the experiment
Outstanding repeatability and reproducibility
Support LIMS system, automatically obtain test results according to specified test methods, and support current and historical LIMS transmission.
Ultra modern and low-cost test instruments, easy to operate and maintain. Easily and quickly evaluate the oxidation resistance of samples.
Using the unique measuring principle, the test instrument can provide reliable results, and manually accelerate the oxidation process by increasing the temperature and excess pure oxygen. With less than five minutes of measurement setup, the lab can be easily wiped clean and the test time is infinitely faster than conventional methods. The fully automatic function can also reduce the workload of the experimenter.
The human-computer interface of the instrument can prompt and guide the operator to operate, and display the test results and test status and other information. All valves operate automatically without manual participation in the whole experimental process.
